Technical Field

[0001] The invention relates to the technical field of metal cleaner production, and in particular to a metal cleaner production device. Background Art

[0002] In the process of producing high-purity titanium dioxide, dilute hydrochloric acid is produced as a byproduct. In the existing technology, the byproduct dilute hydrochloric acid is usually treated by acid-base neutralization and then discharged in compliance with the standards. In order to save resources and improve the circular economy benefits of the industrial chain, the current research and development technology is used to recycle and reuse the byproduct dilute hydrochloric acid. Sodium citrate, polyacrylic acid and other environmentally friendly additives are added to the byproduct dilute hydrochloric acid. The metal cleaner produced is widely used in the cleaning and processing industries of metal products, auto parts, ships and warships, door and window profiles, etc.

[0003] When preparing metal cleaners, auxiliary agents that need to be added include environmentally friendly high-tech liquids such as penetrants, surfactants, and brightening factors. The finished metal cleaner has a certain viscosity, and there may be uneven mixing, inconsistent material concentrations and contents. Therefore, after the metal cleaner is prepared, it is necessary to sample and test the reaction liquid to confirm that the reaction liquid in all parts of the reaction tank is evenly mixed. However, the existing sampling device usually has a sampling point at the bottom outlet of the reaction tank, and the sampling needs to be intercepted repeatedly. Otherwise, the consistency of the product in the entire tank cannot be ensured, and thus the consistency of the quality of each bottle of product during canning cannot be ensured. Summary of the invention

[0006] By adopting the above technical scheme, a corrugated hose, an indicator rod and a telescopic part are provided. When the stirring of the reaction liquid is completed, the corrugated hose and the indicator rod are driven to rise and fall by the telescopic part for multiple times. According to the height indicated by the top of the indicator rod, it is confirmed that the bottom end of the corrugated hose is located at different positions in the tank body, and then the air suction pipe is opened to suck the reaction liquid in the tank body into the liquid collection chamber. Then, the second liquid collection pipe and the air inlet pipe are opened to sample and test the reaction liquid. After the sampling is completed, the second liquid collection pipe is closed to allow excess reaction liquid to flow back into the tank body. Through multiple sampling operations, the reaction liquid at different positions in the tank body can be sampled and tested to confirm that the reaction liquid at different positions in the tank body is evenly mixed, thereby ensuring the consistency of product quality. At the same time, by arranging the indicator rod to rise and fall synchronously with the corrugated hose, the position of the liquid suction port at the bottom end of the corrugated hose in the tank body can be judged from the position of the top of the indicator rod, thereby determining the position of liquid collection, and accurate sampling of the reaction liquid at the required position can be achieved, which facilitates the standardization of sampling operations.

[0010] By adopting the above technical solution, a first rotating ring, a telescopic sheet, etc. are provided. When it is necessary to sample the reaction liquid at different positions, the first driving member is opened to drive the stirring shaft to rotate. When the stirring shaft rotates, the lifting cylinder is driven to rise and fall along the two-way thread, thereby driving the first connecting rod and the first rotating ring to rise and fall. Since the first rotating ring is engaged with the first connecting groove and the second connecting groove, the first rotating ring will drive the corrugated hose and the indicator rod to rise and fall, thereby realizing the adjustment of the height of the liquid suction port at the bottom end of the corrugated hose. Therefore, the height of the corrugated hose and the indicator rod is adjusted by driving the stirring shaft to rotate. On the one hand, the structure can be made more compact, avoiding the telescopic member from affecting the normal rotation and stirring process of the stirring shaft in the tank body. On the other hand, there is no need to add an additional power device, thereby realizing multiple uses of the stirring shaft.

[0011] The present invention is further configured as follows: the first driving member includes a first gear arranged on the top of the first stirring shaft and a driving rod arranged on the top of the tank body and rotating in a vertical direction, the driving rod is provided with a second gear meshing with the first gear, and the tank body is provided with a driving motor for driving the driving rod to rotate.

[0012] By adopting the above technical solution, when the stirring shaft needs to be driven, the driving motor is turned on, the driving motor drives the driving rod and the second gear, the second gear drives the first gear to rotate, and then the stirring shaft is rotated, which is simple and convenient to operate.

[0013] The present invention is further configured as follows: a rotating cylinder is rotatably provided on the tank body in a direction coinciding with the central axis of the stirring shaft, both ends of the stirring shaft are movable through the rotating cylinder, a plurality of second connecting rods are arranged at the bottom of the rotating cylinder in a horizontal direction, a third connecting rod is arranged at the end of the second connecting rod in a vertical direction, a plurality of connecting cylinders corresponding to the third connecting rod are arranged at the bottom of the first rotating ring in a vertical direction, the third connecting rod movably passes through the first rotating ring and the adjacent connecting cylinders, a second stirring blade is arranged on the connecting cylinder, a moving cylinder is rotatably provided on the outer wall of the lifting cylinder, the end of the first connecting rod is fixedly connected to the outer wall of the moving cylinder, and a second driving member for driving the rotating cylinder to rotate is arranged on the tank body.

[0014] By adopting the above technical solution, a connecting cylinder, a second connecting rod, etc. are provided, and the second driving member can be opened while the stirring shaft rotates to drive the rotating cylinder to rotate, and then the connecting cylinder and the second stirring blade are driven to rotate through the second connecting rod and the third connecting rod, so that the second stirring blade and the first stirring blade rotate at the same time, thereby improving the mixing effect of the reaction liquid.

[0015] The present invention is further configured as follows: the second driving member includes a third gear rotatably arranged on the driving rod and a large gear ring rotatably arranged on the top of the tank body, the third gear is meshed with the inner side of the large gear ring, and a fourth gear is arranged on the top of the rotating cylinder, and the fourth gear is meshed with the inner side of the large gear ring.

[0016] By adopting the above technical solution, a third gear and a large gear ring are set, and while the stirring shaft rotates, the driving rod drives the third gear to rotate, and then drives the large gear ring and the fourth gear to rotate, thereby driving the rotating drum to rotate. Since the first gear and the second gear have the same rotation direction, and the fourth gear and the third gear have opposite rotation directions, the driving motor can simultaneously drive the stirring shaft and the rotating drum to rotate in the forward and reverse directions (it should be noted that the rotation speeds of the stirring shaft and the rotating drum are inconsistent, and the rotation speeds of the stirring shaft and the rotating drum can be adjusted according to the sizes of the first gear, the fourth gear, etc., and the stirring speed of the rotating drum needs to be less than the rotation speed of the stirring shaft), so that the stirring directions of the first stirring blade and the second stirring blade are opposite, thereby enhancing the mixing intensity of the reaction liquid in the tank body and improving the mixing efficiency.

[0017] The present invention is further configured as follows: the second stirring blade is located on a side of the connecting tube close to the first stirring blade.

[0018] By adopting the above technical solution, the second stirring blade is located on the side close to the first stirring blade, so that when the first stirring blade and the second stirring blade are stirring, convection is formed between the reaction liquid around the stirring shaft and the reaction liquid around the connecting tube, thereby increasing the stirring intensity of the reaction liquid and further improving the stirring efficiency.

[0019] The present invention is further configured as follows: a T-shaped scraper is provided on one side of the connecting tube close to the tank body.

[0020] By adopting the above technical solution, a scraper is set, so that the connecting tube scrapes the inner wall of the tank body when driving the scraper to rotate, which can not only improve the fluidity of the reaction liquid around the inner wall of the tank body, but also prevent the raw materials from adhering to the inner wall of the tank body, thereby improving the mixing effect of the reaction liquid. At the same time, when cleaning the tank body, the scraper can also clean the inner wall of the tank body.

[0023] The present invention is further configured as follows: a second rotating ring is horizontally arranged in the tank body, an end of the second connecting rod is fixedly connected to the inner side of the second rotating ring, and a top end of the third connecting rod is fixedly connected to the second rotating ring.

[0024] By adopting the above technical solution and providing a second rotating ring, the stability of the second connecting rod and the third connecting rod during rotation is improved.

[0025] The beneficial effects of the present invention are:

[0026] 1. By setting up a corrugated hose, an indicator rod, a telescopic part, etc., the reaction liquid at different positions in the tank body can be sampled and tested through multiple sampling operations to confirm that the reaction liquid at different positions in the tank body is evenly mixed, thereby ensuring the quality of the product. At the same time, by setting the indicator rod to rise and fall synchronously with the corrugated hose, the position of the liquid suction port at the bottom end of the corrugated hose in the tank body can be judged from the position of the top end of the indicator rod, thereby determining the position of liquid collection, and realizing accurate sampling of the reaction liquid at the required position, which is convenient for realizing the standardization of sampling operations.

[0027] 2. By setting a first rotating ring, a telescopic piece, etc., when it is necessary to sample the reaction liquid at different positions, the first driving member is opened to drive the stirring shaft to rotate. When the stirring shaft rotates, the lifting cylinder is driven to rise and fall along the two-way thread, thereby driving the first connecting rod and the first rotating ring to rise and fall. Since the first rotating ring is engaged with the first connecting groove and the second connecting groove, the first rotating ring will drive the corrugated hose and the indicator rod to rise and fall, thereby realizing the adjustment of the height of the liquid suction port at the bottom end of the corrugated hose; therefore, the height of the corrugated hose and the indicator rod is adjusted by driving the stirring shaft to rotate. On the one hand, the structure can be made more compact, and the telescopic member can be prevented from affecting the normal rotation and stirring process of the stirring shaft in the tank body. On the other hand, there is no need to add an additional power device, thereby realizing the multiple uses of the stirring shaft.

[0028] 3. By setting the third gear and the large gear ring, etc., when the stirring shaft rotates, the driving rod drives the third gear to rotate, and then drives the large gear ring and the fourth gear to rotate, thereby driving the rotating drum to rotate. Since the first gear and the second gear have the same rotation direction, and the fourth gear and the third gear have opposite rotation directions, the driving motor can simultaneously drive the stirring shaft and the rotating drum to rotate in the forward and reverse directions, so that the stirring directions of the first stirring blade and the second stirring blade are opposite, thereby enhancing the mixing intensity of the reaction liquid in the tank body and improving the mixing efficiency.

[0044] The present invention is further configured as follows: a T-shaped scraper 28 is provided on one side of the connecting tube 23 close to the tank body 1 .

[0045] The present invention is further configured as follows: a scale plate 29 is vertically disposed on the top of the tank body 1 , an indicator plate 30 is horizontally disposed on the top of the indicator rod 10 , and one side of the indicator plate 30 can be movably fitted to the scale plate 29 .

[0047] When the reaction liquid needs to be stirred, the drive motor 19 is turned on, and the drive rod 12b drives the second gear 18 and the third gear 26a to rotate, and then drives the first gear 12a and the fourth gear 27 to rotate, so that the stirring shaft 2a and the rotating cylinder 20 rotate in the forward and reverse directions. Therefore, the first stirring blade 2b and the second stirring blade 24 stir in opposite directions, so that convection is formed between the reaction liquids in the tank body 1, thereby improving the mixing efficiency of the reaction liquid. When the reaction liquid is stirred, the speed of the drive motor 19 is adjusted to reduce the stirring speed of the stirring shaft 2a. When the stirring shaft 2a rotates, the lifting cylinder 16 is driven to rise and fall along the stirring shaft 2a through the bidirectional thread 15, thereby driving the corrugated hose 9 and the indicator rod 10 to rise and fall. Then, according to the height indicated by the indicator plate 30 on the scale plate 29, it is confirmed that the corrugated hose 9 is located at different positions in the tank body 1. When the bottom end of the corrugated hose 9 is at the height required for sampling, the drive motor 19 is turned off, and then the exhaust pipe 7 is opened to make the tank body 1 The reaction liquid in the tank body 1 is sucked into the liquid collection chamber 3b, and then the second liquid collection tube 6 and the air inlet pipe 8 are opened to sample and detect the reaction liquid. After the sampling is completed, the second liquid collection tube 6 is closed to allow the excess reaction liquid to flow back into the tank body 1. Then, the height of the corrugated hose 9 can be adjusted multiple times by controlling the drive motor 19 to perform sampling operations, thereby sampling and detecting the reaction liquid at different positions in the tank body 1 to confirm that the reaction liquid at different positions in the tank body 1 is evenly mixed, thereby ensuring the quality of the product; in addition, the driving motor 19 can simultaneously realize the forward and reverse rotation of the stirring shaft 2a and the rotating cylinder 20, thereby realizing the rotation of the first stirring blade 2b, the second stirring blade 24, and the scraper 28, as well as the lifting and lowering of the corrugated hose 9 and the indicator rod 10, which can not only improve the stirring and mixing efficiency of the reaction liquid, but also can adjust the height of the corrugated hose 9 at a low speed to realize the sampling of the reaction liquid at different positions, making the structures more compact and interrelated with each other, thereby improving the overall practicality of the equipment.

[0048] By providing the first stirring blades 2b and the stirring shaft 2a, when the reaction liquid needs to be stirred, the first driving member 12 can be turned on to drive the stirring shaft 2a to rotate, so that the reaction liquid in the tank body 1 is stirred and mixed by the multiple first stirring blades 2b, which is simple and convenient to operate.

[0049] By providing the first rotating ring 11a, the telescopic piece 11b, etc., when it is necessary to sample the reaction liquid at different positions, the first driving member 12 is opened to drive the stirring shaft 2a to rotate. While the stirring shaft 2a rotates, the lifting cylinder 16 is driven to rise and fall along the bidirectional thread 15, thereby driving the first connecting rod 17 and the first rotating ring 11a to rise and fall. Since the first rotating ring 11a is engaged with the first connecting groove 13 and the second connecting groove 14, the first rotating ring 11a will drive the corrugated hose 9 and the indicator rod 10 to rise and fall, thereby realizing the adjustment of the height of the bottom end liquid suction port of the corrugated hose 9. Therefore, the height of the corrugated hose 9 and the indicator rod 10 is adjusted by driving the stirring shaft 2a to rotate. On the one hand, the structure can be made more compact, avoiding the telescopic member 11 from affecting the normal rotation and stirring process of the stirring shaft 2a in the tank body 1. On the other hand, there is no need to add an additional power device, thereby realizing the multiple uses of the stirring shaft 2a.

[0050] By setting the driving motor 19 and the first gear 12a, when the stirring shaft 2a needs to be driven, the driving motor 19 is turned on, the driving motor 19 drives the driving rod 12b and the second gear 18, and the second gear 18 drives the first gear 12a to rotate, thereby realizing the rotation of the stirring shaft 2a, and the operation is simple and convenient.

[0051] By providing a connecting cylinder 23, a second connecting rod 21, etc., the second driving member 26 can be opened while the stirring shaft 2a rotates to drive the rotating cylinder 20 to rotate, and then the connecting cylinder 23 and the second stirring blade 24 are driven to rotate through the second connecting rod 21 and the third connecting rod 22, so that the second stirring blade 24 and the first stirring blade 2b rotate at the same time, thereby improving the mixing effect of the reaction liquid.

[0052] By setting the third gear 26a and the large gear ring 26b, etc., when the stirring shaft 2a rotates, the driving rod 12b drives the third gear 26a to rotate, and then drives the large gear ring 26b and the fourth gear 27 to rotate, thereby driving the rotating drum 20 to rotate. Since the first gear 12a and the second gear 18 have the same rotation direction, and the fourth gear 27 and the third gear 26a have opposite rotation directions, the driving motor 19 can simultaneously drive the stirring shaft 2a and the rotating drum 20 to rotate in the forward and reverse directions (it should be noted that the rotation speeds of the stirring shaft 2a and the rotating drum 20 are inconsistent, and the rotation speeds of the stirring shaft 2a and the rotating drum 20 can be adjusted according to the sizes of the first gear 12a, the fourth gear 27, etc., and the stirring speed of the rotating drum 20 needs to be less than the rotation speed of the stirring shaft 2a), so that the stirring directions of the first stirring blade 2b and the second stirring blade 24 are opposite, thereby enhancing the mixing intensity of the reaction liquid in the tank body 1 and improving the mixing efficiency.

[0053] By locating the second stirring blade 24 on the side close to the first stirring blade 2b, convection is formed between the reaction liquid around the stirring shaft 2a and the reaction liquid around the connecting tube 23 when the first stirring blade 2b and the second stirring blade 24 are stirring, thereby increasing the stirring intensity of the reaction liquid and further improving the stirring efficiency.

[0054] By providing the scraper 28, the connecting tube 23 can scrape the inner wall of the tank body 1 when driving the scraper 28 to rotate, which can not only improve the fluidity of the reaction liquid around the inner wall of the tank body 1, but also prevent the raw materials from adhering to the inner wall of the tank body 1, thereby improving the mixing effect of the reaction liquid. At the same time, when cleaning the tank body 1, the scraper 28 can also clean the inner wall of the tank body 1.

[0055] By providing the scale plate 29 and the indicator plate 30, the position of the corrugated hose 9 can be directly indicated, which is convenient for observation.

[0056] By adopting the above technical solution and providing the second rotating ring 31 , the stability of the second connecting rod 21 and the third connecting rod 22 during the rotation process is improved.

[0057] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
